To all whom t may concern. y

Be it known that I, SIMEON C. LAwLom'a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new land useful Improvements in Wringing Appara tus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it'appertains to make. and use thesame. This invention relates to improvements in scrubbing apparatus, and more particularly to wringing attachments for scrub# hing tanks. 1

The object in view is the facilitation of wringing operations underconditions con`` ducive to the attainment of the most reeffort. Y

`With this and further objects in view vras will in part hereinafter become apparent and in part be stated, the invention comprises su'lts Yat a relatively small expenditure'Y of' certain novel constructions, combinationsV and arrangements of 'parts as will be-subsequently specified and claimed.

In the accompanying draw1ngs,

Figure l is a view in side elevation of an"v apparatus embodying the V-features of the present invention. l

Figure 2 is a top plan view thereof, Figures 3 and L are fragmentary Views, the same as Figures 1 and 2,'but'of a slightly different embodiment. Y

Figure 5 is a view similar to-Figure -2 of a still different embodiment, the tank Vbeing omitted.

Referring to the drawingsby numerals, 2 indicates a scrubbing tank which may be of any conventional type, and on the up@ per edge of which is mounted a frame-1. The frame l consistsessentially of a cross bar anda pairA of parallel-arms, the cross bar being shaped'fand adapted to rest upon and-partly enclose the upper edge of one end of tank 2, while the arms extend along and partly enclose the upper fedges'jo'fthe adjacent portions ofthe-sides of the: tank. Jou'rnaled in the arms ofi-frame lis afroller 3 which will hereinafter be referred to as the fixed roller, since, while it is revolubly,

mounted, it is fixed against bodily movement. 'Each' of the arms of frame l is formed with an arcuate track 4: terminating at its forward portion in an elongated notch 4', the upper edge of which notch is formed naled the by'the overhangingportion of a bracketlike upwardv and rearward extension 3. Pendent fr'omfthe rear end portion of. each arm of frame 1 "is a plate 6, each of which rigidly carries nearj its lowerv end a stub shaft'. On thestub'shafts 6 are jourarms of a yoke 6, in the'npper ends of which arms is journa-led a movable roller 5. The location of the shafts 6" and the length of the arms of yvokes 6 are such as-to cause the roller 5 to travelvon the arc described by the tracks 4 when the yoke is swung upon its pivots'G. To tend to cause the V"roller 6 toremain spaced from the roller '8, the yoke 6 is counter-balanced as to the yoke below the Yarm 7 and extending forwardly and upwardly to a point of atitachment' to the tank 2, 'each spring 9 being 'by being provided with an outstanding arm l tensioned to lex'erta stress on theyoke 6k tending'to ykeep the yoke in position Vwith the roller 5 at its rearwardmost location, that is, in theopen position with respect to roller 3. It is,fof course, understood that a closed position of the rollers 3 and 5 is such a position as Vwill cause the rollers to grip a mopk between them'and squeeze the moisture therefrom as ythe mop passes there between. rIhe journal of roller 5 is preferably'extended'atv one end and has an atvtalched crank 5 to enable manual rotation -of rollerv 5 when desired. Cables l0, 10 preferably "of the chain type, areattached to the arms oryoke 6Y and extend upwardly and forwardly"y beneath roller 3 and up over guiding rollerslO, 10- journaled inappropriate "outstanding brackets of';frame 1, the chains V1 0 extending down from the rollers lO1to Y and being connected with' yan operatingv treadle ll.A

vThe "treadle l1 is appropriately itsr'supporting truck'.VY

vI noperation, the roller 5 stands 'normally in thev openil'iosition until the'operator desires to wring the mop orother article to be wrung. The article: is lowered from above down between the rollers 3 and 5, and then the operator places his foot on treadle ll, thus drawing upon the chains l0 and moving the yoke 6 against the stress of springs 9 and weight 8 until the roller 5 'piv'ote'dto'u the 'under Yframe of the tank 2er CII firmly clamps the article between itself and roller 3. journals of roller roll or slide along the tracks fl, and having reached this position the rollers are either manipulated by pulling the mop upward against the resistance of the rollers or by rotating the crank 5. As soon as this wringing operation is completed, the operator r-emoves his foot from the treadle 11 and the roller 5 automatically returns to the open position, ready for the next operation. Itis to be noted that the frame 1 with the parts which it carries is adapted for easy and ready application to any wringing tank already in use, it being understood, of course, that lthe springs V9 must be appropriately attached either to the A tank or to the frame, and the treadle 11 ymust be pivotally mounted.

In Figures 3 an-d 4, the tank, frame, yoke, rollers and roller closing means are arranged the saine as abov'e'described, and the same reference numerals have been applied.

' However, in this construction the counterbalance weight for the yoke 6 is supple,- mented in its action, not by springs, but by a cable 13 which extends over a roller 14 arranged in a bracket outstanding from'the middle portion of the end bar of frame 1, and beyond the roller the chain 13 is provided with a handle ladapted for manual manipulation'.Y The operation of the strucyture is identical with that above described except that when the weight 8 fails to move "i roller 5 to its open position with suiiicient celerity, the operator will grasp the. handle 15 and pull upon it will swing the yoke 6 backward to the open position of the rollers.

VIn Figure 5 is shown a further modification ofthe invention wherein the frame 1b is mounted upon the scrubbing tank and is slightly differently shaped from frame 1 in that in addition to enclosing the upper edge portions of the tank, a plate or platform 26 is provided at` one side and the' tracks 4b are not spaced apart for the full width of the tank by as much as the space occupied by the width of the plate 26. The lfixedY roller 16 is journaled in the frame 1b and Vthe movable roller 17 co-operates with respect thereto after the manner of roller 5, the roller 1'? being journaled ink theV upper Y ends of a yoke 6b which is pivotally `mount- Y 11; Engaging the ,arms of theyoke 6b'subedl in the same manner as yoke 6. Chains v' 18,' engage the yoke 6and extend to an op# erating treadle 19n corresponding. in .form and function with the chains 10 and treadle In coming to this position, the

incontra stantially at the Asame point as do the chains 18 are chains 24 which extend rearward and upward from the yokeV and converge, uniting in achain 21 whichV passes about guiding rollers 23 and 22, 22, and being provided at its forward end with an operating handle or grip 20. The roller 16 in this instance is, provided with an operating crank 5b for rotating the roller when desired, but by preference the roller is power driven by havingV that journal opposite the one carrying crank 5b extended ,and provided with aV sprocket about which ispassed asprocket chain 27- which extends to andl passes about a sprocket driven by an electricfmotor 25. The said motor isrigidly mounted on the platform 0r plate 26. In this construction, the wringv` ing operation is effected bywmerely turning on the current after `the/mop has been placed between the rollers and clamped therebetween. |The clamping action is effected by pressing down the treadle 19 just the same as the operation of treadle 11. After ra. wringing operation has been completed, the operator gives a pull on the handle 2O which swings the'yoke 6b rearward and thus moves the roller VY17 to the open position. YI lihile .the yoke 6b isnot shown counter-balaneed,v

it obviously may be when desired.

It is apparent, of course, that the inven- I tion is susceptible of embodiment in various balancing means connected to the yokeand v stressing the same in a direction for moving the roller carried thereby away from the fixed roller, the frame being formed with an exposed, arcuate track for each journal of the movable roller, each of said tracksterminating in an elongated guiding notch {iaring outward and leading from la lpoint adjacent the respective journal of the iixedV roller, and means for movingV `the yoke against the stress vof the counter-balance.
